- Wed Oct 21, 2009 2:25 am #151979 ok my 92 dx hatch (d15b7) started to run weird yesterday,when its cold it runs fine, but after it warms up it sounds like its running on 3 cylinders, it does it off and on all day, i suspect a clogged injector or fuel filter, any tips? it doesnt do it all the time im just curious to what it might be? any tips are greatly appreciated. :thumb:

- Wed Oct 21, 2009 3:11 am #152002 im not completely sure here but could it possibly be that one of the valves is too tight so when it warms up its not opening long enough?? i mean i think that would do what your saying it is doing occasionally but not completely sure just a thought.

- Wed Oct 21, 2009 3:39 am #152013 the symptoms you describe are exactly that of bad plug wires. I'd spend 5 mins swapping out wires with another car just for a piece of mind. Trade wires for a couple days and see if your car is ok and if the problem happens in the other car.

Also does your dash have a check engine light from this happening?

- Sun Nov 01, 2009 4:59 pm #154149 check the copper "ground" wire bolted to the valve cover, I believe this is what grounds the plug wires, it could be loose and fails when the motor is warmed up. or it could also be your a/c pressure switch shutting your compressor on & off too frequently; if your a/c is still hooked up.
